I have plenty of friends who have kids. That started happening when I was fifteen. I love all those cute little shits. They're like my nieces and nephews. Still, I can relate to what Clint is saying, and I think we all know what he's talking about. I see Dave Martin at shows all the time, stand up dude, you can just tell he's a great father, also down for "the cause." Clint's talking about small town shit though. That shit is depressing. And, ya know, it doesn't always take a whole lot of passion or love for those types to raise a family either.
I don't really know what Clint's point was other than "man, that's kinda depressing, people my age trading their dreams for empty lives that they fill with offspring" which, like I said, I can certainly relate to.
